PNP: remove some uses of DEBUG ifdef

Browse Source 
Use scnprintf() to build up a buffer of PNP IDs to print.  This
makes the printk atomic and helps get rid of an #ifdef.

Also remove an "#ifdef DEBUG" from some debug functions.  The
functions only produce debug output, so it's OK to run the
function and just have the output be dropped at the end.
